ruRNAoni f Be it known that l, lVi'LLrAM 'FRANKLIN PAYNE, a subject ofthe King or Great Brit aimi-esiding at lthe 'c ityofStrattord, in theProvince of` Ontario' n and `Dominion oi? usetul improvements inFurnaces', 4ot which the following isa specification. This inventionrelates to'improvements yin furnaces, and the objects of the inventionare to secure an increased eiiiciency in thev distribution otheat,particuiarly in domesticr furnaces andthose designediortheheatin/iij of houses and buildings', whether hot air or hot Water.

More particular objects oi" the invention are toA insure that themaxin'iu'm amount otY heat. units in the original combustiblegmate-Vrial is transferred to the'. conducting me-y dium, such as the air orWater by Whichitis conductedto the parts are to be heated.f f

are to insure that the heating current of air or Water should be heatedto as hi glia temv peiature as possible before leaving the iurnaceandythat the products ot combustion oi the fire in the furnace shouldremain'in contactwith the air heatingmeans 'as long as possible'betoreleaving the furnace. 1 Further and vmore general objects ot theinvention are generally to simplify and improve the construction oftheffurnace to better adapt it to perform the functions required -ot itand it consists essentially Voit the improved construction andarrangement ot parts hereinafter described `in detail in theaccompanying specification and drawings.

Fuel maybe `charged into thefire pot through the l' yThe products of combustion ifrom'the lire inthefire pot arey adapted at the top of the turna-ce to be dividedy bypartition plate and more particularly tothe i'oim of the invention shownenceindicate ycorresponding parts in all the convenientv designand B'thegrate therein;V`

`will drop through the grate into the ash pit 1U from which they may bedrawn through which will cause them to pass along channels 15' and16.-tlie"outer side of thechannels 'being` formedby air chambers -F andG which' are thus heatedby the products of combustion, these chambersbeingprolvided `with bevelled faces 17 at the forward endend withrounded faces 18 at the rear?y mostfend. The'products of combustion pass:trom the channels 15 and 16 to the down iues 19 and 2() which form partof the inner casing H of the furnace. t the bottom of the inner casingithedoivn ilues communicate with forwardly `extending passageivays 21`through thefreturn iiue 25 to the jup flue 26 1 at the back ofthe casingand from thence to the smoke pipe J Which leads to a suitable'r chimney.During progress of the products` oit combustion in this Way, the heatunits therein will be imparted to the air chambers F, G and I. indicatesone of the air heat ingY pipes Which rises from a `suitable point in theroom to be heated` i I find it convenient to locate the opening oi thispipe'about threeinches `irointhe iioor. ltthen extends into: the airheating chamber Ifand While in ico Avheating chamber' F or G. Thesechambers F and Gr are each provided with a' plurality of outlets 27which when the inner casing is not enclosed by the outer `casing willpermit the heated air to pass directly into the room to be heated. It ispreferable, however7 to enclose the inner casing by an outer casing Ospaced therefrom and fromy 'which pipes P may lead to the rooms orplac'e toy be heated. 1t Vwill be lseen that the air drawn `into thepipes K and Mis heated thoroughly in the heating chamber 1 by passingthrough the serpentine coils and is finally further heated in the airchambers F and G. e

A hinged damper Q 'of any convenient lform may be provided adjacent toan openving 28 leading from the back of the channels 15 and 16 tothe upflue 26. 1f desired, a certain part of the products of combustion passdirectly to the smoke pipe. This `will enable the fire to be startedvmore readily. The damper may be y controlled by a rod 29 connectedthereto extending through the side of the inner casing and being formedwith a crank 30 on the end by vwhich it may be operated.` the saidcrank, if desired, being connected to the operating'rod 31 leading tothe forward lpart of the furnace.

For convenience in gaining access tothe fire pot, an opening 32 be,provided in the top Vof the casing inwardly closed by the plate 33. Theinner casingitself may be supported from the floor or from any suitablebase or 4legs 34.

The alternative form of theA invention shown in Figures 6 and 7illustrates the in vention as applied to water heating systems. In thiscase, the return pipes of the water heating systems are 'connected toserfire pot 48 pass.

pentine coils 440 and 41within the oven 42 which corresponds to theheating chamber I and is heated by the means described with 'respect toth'e form shown in Figures 1 te The outlet conduits 43 and 44 from thecoils 40 and 41 pass to further serpentine `coils 45 and 46 located in achamber 47 through which the product-sof combustion from the It will beseen that in the forni shown in Figures 1 to 5 the cold air will. drawinto the casing at the bottom from the different rooms and as it passesthrough the serpentine coils and air heating chambers, is thoroughlyheated and will become very hot. The conduits 45 and 46, for conveniencein distribution, may be connected *byy the Y branches 48 and 49of aheader` 50 larged from the bottom to the top and having apluralityfofdistributing pipes 52 eX- Vtending from the top thereof and the saineheader may be provided on the return end to combine the pipes from a`plurality of rooms int'o two lconduits which lead to the serpentinelcoilsn40 and 41.

1n addition to this, there is a certain radiation of heat from the`inner casing itself which Vwill either heat the room in which it isplaced or will heat the air in the outer casing. It is found by thismeans possible to effect a considerable economy in the fuel used to heata building of given size.

As many changes vcould be made rin the above construction and manywidely ldifferent embodiments of my invention within the scope of theclaims, constructed without n departing from the spirit or scopethereof, it is intended that all matter contained in the accompanyingspecification and drawings shall be interpreted as illustrative and notin a limiting sense.
